David and I made up this recipe last night -- he did the greens, and I did the beef and onions:
Marinate 2 or 3 small flank steaks in lime juice + pulp, chili sauce, kecap manis, soy sauce and honey. (Approx 2 limes, 1 Tbs chili sauce, 2 Tbs kecap manis, 2 Tbs soy, 1 Tbs honey, but I just drizzled it into the bowl without measuring.) Grill on the BBQ or sear in a pan, then slice up for your salad.
Slice 2 onions and brown on the BBQ plate or in the pan. Set aside.
Simmer the marinade on low in the pan until thickened (approx 3-5 minutes). Return the onions to the pan and toss to coat. If there's a lot of sauce then you can also toss in the sliced beef.
Serve warm on a bed of mixed lettuces, fresh basil, tomato wedges & freshly toasted walnuts lightly dressed with sesame oil, fish sauce & rice vinegar.
